1 nigel 41 Compiling PCRE on non-Unix systems
2     ----------------------------------
3    
4 nigel 75 See below for comments on Cygwin or MinGW and OpenVMS usage. I (Philip Hazel)
5     have no knowledge of Windows or VMS sytems and how their libraries work. The
6     items in the PCRE Makefile that relate to anything other than Unix-like systems
7     have been contributed by PCRE users. There are some other comments and files in
8     the Contrib directory on the ftp site that you may find useful. See

11 nigel 41
12 nigel 73 If you want to compile PCRE for a non-Unix system (or perhaps, more strictly,
13 nigel 75 for a system that does not support "configure" and "make" files), note that
14     PCRE consists entirely of code written in Standard C, and so should compile
15     successfully on any system that has a Standard C compiler and library.

18     GENERIC INSTRUCTIONS
19    
20     The following are generic comments about building PCRE. The interspersed
21     indented commands are suggestions from Mark Tetrode as to which commands you
22     might use on a Windows system to build a static library.
23    
24 nigel 43 (1) Copy or rename the file config.in as config.h, and change the macros that
25     define HAVE_STRERROR and HAVE_MEMMOVE to define them as 1 rather than 0.
26     Unfortunately, because of the way Unix autoconf works, the default setting has
27 nigel 53 to be 0. You may also want to make changes to other macros in config.h. In
28     particular, if you want to force a specific value for newline, you can define
29     the NEWLINE macro. The default is to use '\n', thereby using whatever value
30     your compiler gives to '\n'.
31 nigel 41
32 nigel 75 rem Mark Tetrode's commands
33     copy config.in config.h
34     rem Use write, because notepad cannot handle UNIX files. Change values.
35     write config.h
36    
37 nigel 43 (2) Copy or rename the file pcre.in as pcre.h, and change the macro definitions
38     for PCRE_MAJOR, PCRE_MINOR, and PCRE_DATE near its start to the values set in
39     configure.in.
40    
41 nigel 75 rem Mark Tetrode's commands
42     copy pcre.in pcre.h
43     rem Read values from configure.in
44     write configure.in
45     rem Change values
46     write pcre.h
47    
48 nigel 43 (3) Compile dftables.c as a stand-alone program, and then run it with
49 nigel 73 the single argument "chartables.c". This generates a set of standard
50     character tables and writes them to that file.
51 nigel 41
52 nigel 75 rem Mark Tetrode's commands
53     rem Compile & run
54     cl -DSUPPORT_UTF8 dftables.c
55     dftables.exe > chartables.c
56    
57 nigel 43 (4) Compile maketables.c, get.c, study.c and pcre.c and link them all
58 nigel 41 together into an object library in whichever form your system keeps such
59 nigel 63 libraries. This is the pcre library (chartables.c is included by means of an
60 nigel 73 #include directive). If your system has static and shared libraries, you may
61     have to do this once for each type.
62 nigel 41
63 nigel 75 rem Mark Tetrode's commands, for a static library
64     rem Compile & lib
65     cl -DSUPPORT_UTF8 -DPOSIX_MALLOC_THRESHOLD=10 /c maketables.c get.c study.c pcre.c
66     lib /OUT:pcre.lib maketables.obj get.obj study.obj pcre.obj
67    
68 nigel 73 (5) Similarly, compile pcreposix.c and link it (on its own) as the pcreposix
69     library.
70 nigel 41
71 nigel 75 rem Mark Tetrode's commands, for a static library
72     rem Compile & lib
73     cl -DSUPPORT_UTF8 -DPOSIX_MALLOC_THRESHOLD=10 /c pcreposix.c
74     lib /OUT:pcreposix.lib pcreposix.obj
75    
76 nigel 43 (6) Compile the test program pcretest.c. This needs the functions in the
77 nigel 41 pcre and pcreposix libraries when linking.
78    
79 nigel 75 rem Mark Tetrode's commands
80     rem compile & link
81     cl pcretest.c pcre.lib pcreposix.lib
82    
83 nigel 43 (7) Run pcretest on the testinput files in the testdata directory, and check
84 nigel 41 that the output matches the corresponding testoutput files. You must use the
85 nigel 63 -i option when checking testinput2. Note that the supplied files are in Unix
86     format, with just LF characters as line terminators. You may need to edit them
87     to change this if your system uses a different convention.

90     rem Make a change, i.e. space, backspace, and save again - do this for all
91     rem to change UNIX to Win, \n to \n\r

94     write testoutput3

108    
109     FURTHER REMARKS
110    
111 nigel 41 If you have a system without "configure" but where you can use a Makefile, edit
112     Makefile.in to create Makefile, substituting suitable values for the variables
113     at the head of the file.
114    
115     Some help in building a Win32 DLL of PCRE in GnuWin32 environments was
116 nigel 63 contributed by Paul Sokolovsky. These environments are Mingw32
117     (http://www.xraylith.wisc.edu/~khan/software/gnu-win32/) and CygWin
118     (http://sourceware.cygnus.com/cygwin/). Paul comments:
119 nigel 41
120     For CygWin, set CFLAGS=-mno-cygwin, and do 'make dll'. You'll get
121     pcre.dll (containing pcreposix also), libpcre.dll.a, and dynamically
122     linked pgrep and pcretest. If you have /bin/sh, run RunTest (three
123     main test go ok, locale not supported).
124    
125 nigel 63 Changes to do MinGW with autoconf 2.50 were supplied by Fred Cox
126     <sailorFred@yahoo.com>, who comments as follows:
127    
128     If you are using the PCRE DLL, the normal Unix style configure && make &&
129     make check && make install should just work[*]. If you want to statically
130     link against the .a file, you must define PCRE_STATIC before including
131     pcre.h, otherwise the pcre_malloc and pcre_free exported functions will be
132     declared __declspec(dllimport), with hilarious results. See the configure.in
133     and pcretest.c for how it is done for the static test.
134    
135     Also, there will only be a libpcre.la, not a libpcreposix.la, as you
136     would expect from the Unix version. The single DLL includes the pcreposix
137     interface.
138    
139     [*] But note that the supplied test files are in Unix format, with just LF
140     characters as line terminators. You will have to edit them to change to CR LF
141     terminators.
142    
143     A script for building PCRE using Borland's C++ compiler for use with VPASCAL
144     was contributed by Alexander Tokarev. It is called makevp.bat.
145    
146     These are some further comments about Win32 builds from Mark Evans. They
147     were contributed before Fred Cox's changes were made, so it is possible that
148     they may no longer be relevant.
149    
150 nigel 73 "The documentation for Win32 builds is a bit shy. Under MSVC6 I
151 nigel 63 followed their instructions to the letter, but there were still
152     some things missing.
153    
154     (1) Must #define STATIC for entire project if linking statically.
155     (I see no reason to use DLLs for code this compact.) This of
156     course is a project setting in MSVC under Preprocessor.
157    
158     (2) Missing some #ifdefs relating to the function pointers
159     pcre_malloc and pcre_free. See my solution below. (The stubs
160 nigel 73 may not be mandatory but they made me feel better.)"
161 nigel 63
162     =========================
163     #ifdef _WIN32
164     #include <malloc.h>
165    
166     void* malloc_stub(size_t N)
167     { return malloc(N); }
168     void free_stub(void* p)
169     { free(p); }
170     void *(*pcre_malloc)(size_t) = &malloc_stub;
171     void (*pcre_free)(void *) = &free_stub;
172    
173     #else

175     void *(*pcre_malloc)(size_t) = malloc;
176     void (*pcre_free)(void *) = free;

182     BUILDING PCRE ON OPENVMS
183    
184     Dan Mooney sent the following comments about building PCRE on OpenVMS:
185    
186     "It was quite easy to compile and link the library. I don't have a formal
187     make file but the attached file [reproduced below] contains the OpenVMS DCL
188     commands I used to build the library. I had to add #define
189     POSIX_MALLOC_THRESHOLD 10 to pcre.h since it was not defined anywhere.
190    
191     The library was built on:
192     O/S: HP OpenVMS v7.3-1
193     Compiler: Compaq C v6.5-001-48BCD
194     Linker: vA13-01
195    
196     The test results did not match 100% due to the issues you mention in your
197     documentation regarding isprint(), iscntrl(), isgraph() and ispunct(). I
198     modified some of the character tables temporarily and was able to get the
199     results to match. Tests using the fr locale did not match since I don't have
200     that locale loaded. The study size was always reported to be 3 less than the
201     value in the standard test output files."
202    
203     =========================
204     $! This DCL procedure builds PCRE on OpenVMS

215     $! I had to set POSIX_MALLOC_THRESHOLD to 10 in PCRE.H since the symbol

229     $! Arguments must be enclosed in quotes.
230     $ PCRETEST "-C"
231     $! Test results:
232     $!
233     $! The test results did not match 100%. The functions isprint(), iscntrl(),
234     $! isgraph() and ispunct() on OpenVMS must not produce the same results
235     $! as the system that built the test output files provided with the
236     $! distribution.
237     $!
238     $! The study size did not match and was always 3 less on OpenVMS.
239     $!
240     $! Locale could not be set to fr
